If your Microsoft Edge is having problems playing Flash videos in Microsoft Edge, you have come to the right place.
The browser’s settings indicated to “Use Adobe Flash Player”,
but when going to https://helpx.adobe.com/flash-player/kb/flash-player-issues-windows-10-edge.html and https://helpx.adobe.com/flash-player.html,
it failed the “Test Flash Player” test.
Flash is integrated into Internet Explorer and Microsoft Edge in Windows 10.
The problem could be that the flash files on your computer are corrupt.
Resolution: Replace the flash files from another Windows 10 computer.
The two folders that need to have their files replaced are:
C:\Windows\System32\Macromed\Flash and C:\Windows\SysWOW64\Macromed\Flash
There may be security issues trying to delete the old files and adding the replacement files, so be sure to change the security settings ownership of both Flash folders to a user (like EVERYONE) that will give you the permissions.
